Subject: RE: [keycloak-dev] Customising Keycloak Authentication flow
Thanks for the quick reply.
We are planning to authenticate a device(client) which will come with its
certificate. It seems two extension points may not work for the requirement
we have.
The cert implementation for keycloak that is planned may not work for us, as
we need to handle this authentication differently.
For, e.g., we can’t configure the Realm client’s trust store to contain
certificates from all clients. In absence of this we will
need the client to provide its certificate which is signed by a specific CA
root authority and also establish that it owns the private key
for this certificate.
Can you please help us understand
1. what kind of hooks are planned and when they are planned?
We don't know how it'll look like yet. Hopefully this is something we can add by
the end of the year.
In the mean-time I'd suggest you:
1. Create a new jaxrs class with two methods, one that returns the nounce and another that
authenticates the client, look at TokenService as a reference for this, specifically at
TokenService.grantAccessToken.
2. Extend KeycloakApplication to add your new class
3. Create your own auth-server war - see 'project-integrations/aerogear-ups' as a
reference for this
That should allow you to add the functionality you need without having to modify existing
Keycloak code.
2. Will the hook help in building 2-step authentication we
need?(2-step
authentication explained in my initial mail)
Yes, we'll include your use-case when designing the hooks
Thanks,
Lakshmi Narayana V

Afraid at the moment we don't have any proper way to hook into this, but we
are planning to add this in the future.
I'm assuming you're authenticating clients, not users? If so that's
something
we plan to add support for at some point.
We'll probably add two extension points, one for adding custom login for
users (for example a hardware multi-factor auth or even fingerprint scanner)
and another for authenticating clients (certificate, jwt, etc.).
